 In the past 2 days or so, I'm seeing very weird failures during gcc
 rebuild (both in f22 and f23, on x86_64 as well as i686).
 Compare e.g.
 http://koji.fedoraproject.org/koji/taskinfo?taskID=9399430
 and
 http://koji.fedoraproject.org/koji/taskinfo?taskID=9399427
 build.log results (from a scratch rebuild of gcc-5.0.0-0.21.fc2{2,3}) with
 https://kojipkgs.fedoraproject.org/packages/gcc/5.0.0/0.21.fc22/data/logs/
 https://kojipkgs.fedoraproject.org/packages/gcc/5.0.0/0.21.fc23/data/logs/
 built some time ago, at least in the f22 case tcl has not changed, dejagnu
 neither, nor expect.
 And, I can't reproduce myself in mock running on F21 kernel.
 The logs look like if the compiler output (which is emitted to a pseudo
 terminal) is randomly trimmed if it is too large, as if the kernel had
 issues with flushing output to pseudo terminals or something similar.
 Any help in trying to narrow this down appreciated (info if there have
 been kernel upgrades etc.).
